Role of psychological factors in the clinical course of heart transplant patients

Mental Health and Substance Use Disorders in Transplant Waitlist, VAD, and Heart Transplant Patients: A TriNetX Database Analysis

Background/Objectives: Mental health and substance use disorders (MHDs and SUDs) affect cardiac allograft and VAD recipients and impact their quality of life and compliance. Limited research currently exists on MHDs and SUDs in this population. Methods: This study compares the incidence of MHDs and SUDs in the transplant list, VAD, and post-transplant patients with that in heart failure patients. Study cohorts were derived from the TriNetX database using ICD-10 codes. Differences in incidence were examined using the log-rank test. Adults with MHDs and SUDs before the window of time were excluded. All comparisons were made between propensity-matched cohorts. Statistical significance was set at p < 0.05. Results: Transplant waitlist patients showed a significant increase in the incidence of anxiety, depression, panic, adjustment, mood, alcohol use, and eating disorders. Post-transplant patients showed a significant increase in depression and opioid use. VAD patients showed a significant increase in depression and a decrease in panic disorder and anxiety. These results allow for further investigations on prevention and coping strategies. Conclusions: The deterioration of mental health can significantly impact medication compliance, survival, and quality of life. Opioid use for pain management in the early postoperative period should be further investigated to assess its impact on long-term substance use and addiction.

Depressive symptoms at 1 year after surgery increase the risk of cardiac allograft vasculopathy and mortality in heart transplant recipients: A prospective cohort study

OBJECTIVE

To investigate the impact of depressive symptoms at 1-year post-heart transplant (HTx) on cardiac allograft vasculopathy (CAV) and mortality.

METHODS

We performed a single-center prospective cohort study of patients 1-year post-HTx consecutively enrolled between January 2001 and September 2015, and followed-up until November 2020. Kaplan-Meier and uni- and multivariate cox proportional hazards models were used to investigate the impact of depressive symptoms (Beck Depression Inventory) on all-cause mortality and clustered CAV events, i.e. time to angiographically detected CAV, revascularizations, retransplantation/CAV-mortality.

RESULTS

23.7% (45/190) (median age 53.5 [IQR 19.3], 77% men) had mild to severe depressive symptoms (BDI 10-63). Forty-four patients (23.2%) died during a 10.4 years median follow-up. Depressive symptoms (BDI ≥ 10) increased all-cause mortality risk (HR = 2.52 [1.35-4.71], p = .004), even after adjusting for confounders (HR = 2.95 [1.50-5.80], p = .002). CAV data were available for 156 patients. During a 9.9 years median follow-up, 51 patients (32.7%) developed CAV or revascularization of which 8 received at least a second revascularization, 3 were re-transplanted, and 9 died from CAV-related causes. Analysis showed a significant increased CAV-risk among depressed patients (HR = 2.27 [1.10-4.69], p = .026), even in adjusted models (HR = 2.25 [1.01-4.98, p = .047).

CONCLUSION

Depressive symptoms at 1-year post-HTx unfavorably impact mortality and CAV, highlighting the need for interventions.

The Predictive Value of Depression in the Years After Heart Transplantation for Mortality During Long-Term Follow-Up

OBJECTIVE

Current understanding of the prognostic impact of depression on mortality after heart transplantation (HTx) is limited. We examined whether depression after HTx is a predictor of mortality during extended follow-up. Subsequently, we explored whether different symptom dimensions of depression could be identified and whether they were differentially associated with mortality.

METHODS

Survival analyses were performed in a sample of 141 HTx recipients assessed for depression, measured by self-report of depressive symptoms (Beck Depression Inventory - version 1A [BDI-1A]), at median 5.0 years after HTx, and followed thereafter for survival status for up to 18.6 years. We used uni- and multivariate Cox proportional hazard models to examine the association of clinically significant depression (BDI-1A total score ≥10), as well as the cognitive-affective and the somatic subscales of the BDI-1A (resulting from principal component analysis) with mortality. In the multivariate analyses, we adjusted for relevant sociodemographic and clinical variables.

RESULTS

Clinically significant depression was a significant predictor of mortality (hazard ratio = 2.088; 95% confidence interval = 1.366-3.192; p = .001). Clinically significant depression also was an independent predictor of mortality in the multivariate analysis (hazard ratio = 1.982; 95% confidence interval = 1.220-3.217; p = .006). The somatic subscale, but not the cognitive-affective subscale, was significantly associated with increased mortality in univariate analyses, whereas neither of the two subscales was an independent predictor of mortality in the multivariate analysis.

CONCLUSIONS

Depression measured by self-report after HTx is associated with increased mortality during extended follow-up. Clinical utility and predictive validity of specific depression components require further study.

Analysis of Health Behaviors in Patients After Liver Transplant

Currently, transplantation is one of the most effective treatments for the failure of organs such as liver, kidneys, or heart. Keeping to specific recommendations by organ recipients is extremely important, as they are vital to the effectiveness of the transplant. Positive health behaviors (HBs) have significant impact on strengthening the recipient's health.

AIM

The aim of this work is to indicate which HBs are exhibited by patients after liver transplants.

MATERIALS AND METHODS

The study group consisted of 115 adult liver recipients, in various times after their transplants. The average age in the group was 53.83 years old. The major reason for transplant was post-inflammatory cirrhosis of liver originating from hepatitis B or C viral infection. A diagnostic survey was used in the study, as well as a tool in the form of an original questionnaire and Juczyński's standard Health Behavior Inventory (HBI) questionnaire.

RESULTS

On the scale of general HBI index, patients achieved high results (M = 101), which shows that most recipients were disciplined in adhering to HBs. The worst results were achieved in the category of good eating habits, which proves that some respondents do not keep to the principles of healthy eating. The longer the time after the transplant, the lesser the extent in complying with HBs by recipients, in the first place in the scope of maintaining positive mental attitude. Specific behaviors were slightly worse, especially in residents of the countryside.

CONCLUSIONS

Adherence to particular categories of health strengthening behaviors is conditioned by specified sociodemographic variables. Sex, level of education, and professional status significantly affect the implementation of pro-health activities. These are best implemented by women who had completed university and high school education who are on a pension or retired.

Preparation and Support of Patients through the Transplant Process: Understanding the Recipients' Perspectives

Preparation for heart transplant commonly includes booklets, instructional videos, personalized teaching sessions, and mentorship. This paper explores heart transplant recipients' thoughts on their preparation and support through the transplant process. Twenty-five interviews were audio-/videotaped capturing voice and body language and transcribed verbatim. Coding addressed language, bodily gesture, volume, and tone in keeping with our visual methodology. Recipients reported that only someone who had a transplant truly understands the experience. As participants face illness and life-altering experiences, maintaining a positive attitude and hope is essential to coping well. Healthcare professionals provide ongoing care and reassurance about recipients' medical status. Mentors, family members, and close friends play vital roles in supporting recipients. Participants reported that only heart transplant recipients understood the experience, the hope, and ultimately the suffering associated with living with another persons' heart. Attention needs to be focused not solely on the use of teaching modalities, but also on the development of innovative support networks. This will promote patient and caregiver engagement in self-management. Enhancing clinicians' knowledge of the existential aspects of transplantation will provide them with a nuanced understanding of the patients' experience, which will ultimately enhance their ability to better prepare and support patients and their caregivers.

Qualitative interviews vs standardized self-report questionnaires in assessing quality of life in heart transplant recipients

Quality of life (QoL) studies in heart transplant recipients (HTRs) using validated, quantitative, self-report questionnaires have reported poor QoL in approximately 20% of patients. This consecutive mixed methods study compared self-report questionnaires, the Medical Outcomes Study 36-item Short Form Health Survey (MOS SF-36) and the Atkinson Life Satisfaction Scale, with phenomenologically informed audiovisual (AV) qualitative interview data in 27 medically stable HTRs (70% male; age 53 ± 13.77 years; time since transplant 4.06 ± 2.42 years). Self-report questionnaire data reported poor QoL and more distress compared with previous studies and normative population samples; in contrast, 52% of HTRs displayed pervasive distress according to visual methodology. Using qualitative methods to assess QoL yields information that would otherwise remain unobserved by the exclusive use of quantitative QOL questionnaires.

Depression in heart failure: biobehavioral mechanisms

The etiology, predictive value, and biobehavioral aspects of depression in heart failure (HF) are described in this article. Clinically elevated levels of depressive symptoms are present in approximately 1 out of 5 patients with HF. Depression is associated with poor quality of life and a greater than 2-fold risk of clinical HF progression and mortality. The biobehavioral mechanisms accounting for these adverse outcomes include biological processes (elevated neurohormones, autonomic nervous system dysregulation, and inflammation) and adverse health behaviors (physical inactivity, medication nonadherence, poor dietary control, and smoking). Depression often remains undetected because of its partial overlap with HF-related symptoms and lack of systematic screening. Behavioral and pharmacologic antidepressive interventions commonly result in statistically significant but clinically modest improvements in depression and quality of life in HF, but not consistently better clinical HF or cardiovascular disease outcomes. Documentation of the biobehavioral pathways by which depression affects HF progression will be important to identify potential targets for novel integrative behavioral and pharmacologic interventions.
